Gene name:
RYBP(DEDAF;YEAF1);
Protein name:
RING1 and YY1-binding protein;
Alternative:
Death effector domain-associated factor(DED-associated factor);Apoptin-associating protein 1(APAP-1);YY1 and E4TF1-associated factor 1;
Organism:
Human (Homo sapiens).
General Annotation
Sub Unit:
Monomer. Interacts with apoptin, DEDD, FADD, CASP8, CASP10, YY1 and GABPB1. Component of repressive BCOR complex containing Polycomb group subcomplex at least composed of BCOR, PCGF1, RING1 and RNF2/RING2. Together with GABPB1 and YY1, it forms a ternary complex, probably being the bridge factor between these two transcription factors. Interacts with CBX2, YAF2, RING1 and RNF2. Interacts with ubiquitin and ubiquitinated proteins. Interacts with ubiquitinated histone H2A (By similarity). Interacts with MDM2, and thereby inhibits ubiquitination of TP53. Identified in a ternary complex containing MDM2, TP53 and RYBP.
Function:
Inhibits ubiquitination and subsequent degradation of TP53, and thereby plays a role in regulating transcription of TP53 target genes. May be implicated in the regulation of the transcription as a repressor of the transcriptional activity of E4TF1. May bind to DNA. Promotes apoptosis.
Subcellular Location:

nucleoplasm
Primarily found in the nucleus. Detected in a punctate pattern likely to represent Polycomb group (PcG) bodies.
